High strength and stability: The selected medical-grade stainless steel or titanium alloy, after special treatment, has a tensile strength of more than 800MPa, can withstand large external forces and vibrations, maintain a firm connection during long-term use of medical equipment, and prevent loose components from affecting equipment performance.
Excellent corrosion resistance: The material itself has good corrosion resistance, and the surface is passivated or coated to form a dense protective layer, which can effectively resist the erosion of disinfectants, acid and alkali substances and human body fluids in the medical environment, prevent rivets from rusting and breaking, and extend the service life of the equipment.
High precision and adaptability: It is manufactured using a high-precision cold heading process, with a dimensional accuracy of ±0.01mm, which accurately matches the hole position of medical equipment components. At the same time, it provides a variety of diameters (1.5mm - 6mm) and lengths (3mm - 20mm) to meet the connection needs of parts of different thicknesses and materials.

Biosafe and reliable: Strictly following the ISO 10993 biosafety standard, the material is non-toxic, non-allergenic, and safe for contact with the human body. It can be safely used in medical devices that come into direct contact with patients, such as connecting the housing of rehabilitation equipment and fixing surgical instrument components.

Product Details
Material and process: 316L medical stainless steel and titanium alloy are mainly used. 316L stainless steel is vacuum melted to improve purity, and is formed in one step through cold heading process to ensure uniform density and strength of rivets; titanium alloy rivets use a combination of hot die forging and cold extrusion to optimize the internal structure. Surface treatment uses electrolytic polishing, passivation or PVD coating technology to reduce surface roughness to Ra≤0.4μm, enhancing smoothness and protective performance.
Specifications and customization: Standard specification products are provided, with diameters covering 1.5mm, 2mm, 2.5mm, 3mm, 4mm, 5mm, 6mm, and lengths ranging from 3mm to 20mm. At the same time, customized services are supported, and the rivet head shape (such as countersunk head, flat head, semi-circular head), dimensional accuracy, surface treatment method, etc. can be adjusted according to customer needs to meet the personalized design and manufacturing requirements of medical equipment.
Application scenarios: In the field of surgical instruments, it is used to connect the joints of surgical forceps and tweezers to ensure flexible operation and stable structure; in medical imaging equipment, it is used to fix the rack, protective cover and other components to ensure that the equipment is not shaken or noisy during operation; in rehabilitation training equipment, it is used to connect the frame and active parts to help patients with safe training. In addition, it can also be used in the production of medical consumables, such as the assembly and fixation of syringes and infusion sets.
